Building Instructions for the Raven eCCPM helicopter kits.
Introduction
Congratulations on your purchase of Century Helicopter Product's newest RC helicopter model. The
Raven eCCPM is a new breed of helicopter, ideal for beginners new to the hobby through to
expert pilots. In order for our helicopters to improve, we needed to provide higher value for a
better price, but this needed revising. Our result is this kit you are about to start building,
offering the best design and quality of the 30 and 50 class and including features commonly
found only in more expensive kits. This kit will exceed your expectations for precision control
at an affordable price.
Warning
This radio controlled model is not a toy! It is a precision machine requiring proper assembly and
setup to avoid accidents. It is the responsibility of the owner to operate this product in a safe manner
as it can inflict serious injury otherwise. It is recommended that if you are doubt of your abilities,
seek assistance from experienced radio control modelers and associations. As manufacturer, we
assume no liability for the use of this product.
Pre-assembly Information
Upon opening the kit, all the major component parts are bagged and numbered for ease of assembly
which correspond to the sections of the manual. Various assemblies have been pre-assembled only
requiring the final assembly and installation onto the particular part, screws and nuts required for
each step are packaged in the same bag as the parts. Be careful when opening each bag as not to lose
any hardware. Care has been taken in filling and packing of each bag however mistakes do happen,

(1)
Collective & Throttle:
Slowly raise the
throttle stick, the helicopter should lift off at half
stick. If it tends not to lift off increase the hover
pitch on the radio or increase the throttle trim. If
the helicopter lifts off before mid stick decrease
these settings.
(2)
Rudder:
When the helicopter is ready to take
off, make a correction trim first then use the
rudder stick to control the Left & Right. Note,
now is a good time to make a final adjustment on
the gyro, see gyro manual.
(3)
Elevator:
If at hover the helicopter tends to
move forward, move the trim down, if it moves
backward move the trim upwards Use the eleva-
tor stick to control the Forward & Backward.
(4)
Roll (Aileron):
If at hover the helicopter
tends to move left, move the trim right, if the
helicopter moves to the right move the trim left.
Move the Aileron stick to control the slide of the
helicopter to the Right & Left.
PRE-FLIGHT CHECK UP & TRIM ADJUSTMENTS
All trim adjustments are to allow you to lift
the helicopter straight up and can be made
one click or detent at a time on the radio.
Hovering
When all is set, ready and checked, attach your training gear/pod and start the engine.
(1) Place the helicopter pointing into the wind and stand behind the model about 15' away.
(2) Always watch the nose of the helicopter, move the rudder left and the nose will move left.
(3) Start by increasing the throttle slowly until the helicopter rises 2-6 inches off the ground then set it back down.
(4) Repeat this process until you become comfortable with the holding the model in the same spot for a few
seconds then land it.
After some time at this you can increase the height slightly up to 1 foot ( be very carefull not to get too high ) as
you are practising taking off and landing. This is the most basic but required skill for the beginner to learn.
Beyond Hovering
It cannot be stressed enough that mastering the hovering skill is crucial to becoming a good helicopter pilot. As
you progress in your learning, always practise hovering until you are completely comfortable in holding the
helicopter in any direction at any altitude. Perfecting hovering enables you to learn all the types and styles of
helicopter flying, forward flight, loops and rolls, 3D (aerobatic flying) and anything you want to do with your
Hawk helicopter as it can be set up for beginner through to expert. Lastly, have fun!!
Basic Hovering
Pre-Flight Checklist
1.
After turning radio on, move each servo separately, looking for unusual or excessive movement.
2.
Lubricate the main shaft above the swashplate and the pitch slider on the tail output shaft with oil.
3.
Inspect the main and tail rotor grips for play or binding.
4.
Turn the main gear in both directions to feel if a problem is developing in the drive train.
5.
Check the glow plug and fuel lines for signs of wear.
